Lyme disease is the most common tick-borne disease in Anne Arundel County, as well as in Maryland and the United States. Cases of Lyme disease are found throughout the county and are not concentrated in any particular area. The county had 91 newly reported cases of Lyme disease in 2018, 121 cases in 2017, 174 cases in 2016 and 107 cases in 2015.
How Is It Spread?
Lyme disease is spread to people from a tiny tick the size of a pinhead known as a blacklegged or deer tick. The tick is hard to see because it is so small. Only about 65% of people in confirmed cases noticed a tick before they became ill. In most cases, the tick needs to be on a person for at least 24 hours before the person becomes infected.
These ticks are most often found from May through October in tall grass, brush and wooded areas. But they can be present, in smaller numbers, throughout the year. Pets can bring ticks into the house. Mice also carry ticks.
What Are The Symptoms?
Symptoms usually start within a month of being infected. About 75% of patients with early Lyme disease will have a skin lesion in the first one to four weeks of infection. Some get a “bull’s eye rash” that has a red center. Other early symptoms may include fever, joint and muscle pains, headache or fatigue. Lyme disease is hard to diagnose because the symptoms often mimic other diseases. Special laboratory tests may be needed to make a diagnosis.
If left untreated, the infection can lead to serious illnesses of the heart, joints and nervous system.
Lyme disease may cause birth defects or miscarriages.
How Can It Be Prevented?
If You Find A Tick
Remove the tick right away, but do not touch it with your bare hands. Use tweezers to grip the tick behind its head and as close to the skin as you can. Gently pull it off. If tweezers are not available, use your fingers wearing gloves or a tissue. Do not smash or burn the tick.
After removing the tick, wash your hands with soap and water or waterless alcohol-based hand rub. Clean the tick bite with an antiseptic such as iodine scrub, rubbing alcohol, or soap and water.
Mark a calendar on the date you found the tick and watch for symptoms for at least a month.
If a rash develops or you experience other symptoms within three to 32 days, call your physician immediately.
